Tips For Clearing Up And Preventing Foggy Windows

January 4th, 2024 by

Most drivers have experienced the annoyance of driving with foggy windows. In some cases, the fogging up of windows is a temporary issue that can be cleared up with little effort. In other cases, however, foggy windows can regularly lead to reduced visibility while driving. 


In this blog post, Headquarter Nissan will share tips for clearing and preventing foggy windows. Stay safe behind the wheel by following these tips!


Car Window Fog: How it Happens?

Most drivers know that humid weather can cause their windows to fog up. When warm, humid air strikes a cold surface, such as a car window, it condenses and forms water droplets. This process is similar to how your glass of ice water “sweats” on a hot day.


Other factors can contribute to car window fogging, as well. For example, suppose you leave your car windows open during humid weather or blast the air conditioning without setting it to recirculate mode.


In that case, you’re more likely to end up with foggy windows. Even something as straightforward as not using a windshield sunshade can cause your windows to fog up!


Clearing Up Foggy Windows

If your windows have already fogged up, there are a few things you can do to clear them up:


  1. Turn on the defroster. This will help circulate dry air around your windows and clear the fog.
  2. Turn off the air conditioning. As we mentioned before, AC can actually contribute to window fogging.
  3. Open your windows. Opening your car windows will help clear up any fog on the glass if it’s not too cold outside.
  4. Use a hankie or paper towel to wipe away any condensation on your windows.
  5. Crack open a window slightly when you turn off your car. This will help to control any condensation from forming overnight.


Preventing Foggy Windows

The best way to deal with foggy windows is to prevent them from happening in the first place.


  1. Make sure your windows are clean. Dirt and grime can contribute to window fogging, so keeping your windows clean is important.
  2. .
  3. Use an anti-fog solution. You can buy these solutions at most auto stores, which can help prevent your windows from fogging up.
  4. Keep the humidity in your car under control. You can do this by using a dehumidifier or keeping a small container of moisture-absorbing beads in your car.
  5. Park in the shade whenever feasible. That will help keep your car cooler and prevent condensation from forming on your windows.
  6. Don’t use your AC too much. As we mentioned, the AC can actually contribute to window fogging. If you don’t need it, try to avoid using it or turn it down as low as possible.
  7. Crack your windows. This will help to circulate air and prevent fogging. Just make sure you crack them enough that you won’t get moisture in your car.
  8. Use a defroster. If your windows are already foggy, you can use your car’s defroster to clear them up. Just make sure to not leave it on for too long, as this can damage your windows.
